# Does Air Resistance Affect The Motion Of A Falling Object Differently When The Initial Velocity Of The (2023)

Physics College

Yes, it does.

We have that air resistance creates a force on falling objects, namely drag. The drag of an object depends on its shape, its cross-section in the direction it is falling, the nature of the air (humind or not) and the velocity of the object. In general, the greater the velocity, the greater the drag; the drag force is against the motion of the body.

Supplementary info: 1)It is also calculated that raindrops and other small objects, when they come down to Earth they develop very high velocities. If we account for drag, the force of drag balances out the force of gravity due to their great velocity and they stop accelerating, they have reached terminal velocity.

2)This is contrary to our experience with friction, that does not depend on velocity almost at all.

Newton discovered that gravity affects the orbits of planets

True
Or
False

Explanation:

Newton was inspired by Kepler's theory to be able to establish his theory about gravity, which is defined as a force that occurs only when there are two bodies with mass. Newton does not give a clear explanation why this situation occurs, since he calls this force as divine, and does not go further in the study of it.

The planets to be solid bodies with mass fall within this dynamics, being so close or gravitating in orbits of planets with greater mass that could cause an affectation of both planets.

False. Kepler discovered this and Newton was inspired by this.

True or False: The absorption of alcohol can be slowed down by eating, but only water can reduce the BAL level.

False

Explanation:

The blood alcohol level cannot be changed by anything but the metabolism or the individual that is drinking the alcohol, and that is a job performed by the liver, so no one can speed up that process, alcohol absorption does change depending on what the person has in their stomach, that is why people get dunker mmore easily when they haven´t have anything to eat before drinking.

If you neglect air resistance, then you can solve for the horizontal distance using the formula:

dx=vixt

Where:
dx = horizontal distance
vix = initial horizontal velocity
t = time in flight

Now you can see that you have all the given you need.
vix= 2km/h
t = 0.25 hours

We use hours because you need the units to be the same. So just plug that in your equation and you will have your answer:

dx = vixt
=(2km/h)(0.25h)
=0.5km

How much heat is absorbed by a 74g iron skillet when its temperature rises from 7oC to 28oC?

The specific heat of iron (assuming the skillet is pure iron) is 0.45 J/g-C. Then we use the equation q = mc(dT) to determine the total heat absorbed. This gives:
q = (74 g)(0.45 J/g-C)(28 - 7 C) = (74)(0.45)(21) = 699.3 J

The correct answer for above statement is:

Seven.Explanation:

Every energy level has a short one orbital including two particles. The orbits are located in the sub-levels and there can be additional than 1 sub-level as the amount of energy levels increases. On power level 1, there is 1 sub-level and 1 orbital. Energy level 2 package hold 2 sub-levels and 2 orbitals. These continue to increase as you advance from the nucleus of the atom, concluding up with an endless potential quantity of levels and departments.

Each energy level has at least one orbital with two electrons. Energy level two can have two subleves and two orbits. But the maximum orbits are 7!

Cleo stated that light travels through air in straight paths, and when it moves from air to water, light changes direction, speeds up, and bends toward the normal.Which statement best describes Cleo’s mistake?

Answer: light slows down when it moves from air into water.

Explanation:

1) As correctly stated by Cleo, the light changes direction when it moves from air to water. That is what is called refraction.

2) Refraction is defined as the bending of the light ray due to the change of medium.

3) Refraction happens as much as the light goes from air to water and as water goes from water to air.

4) Since the water is an optically denser medium than air, the light ray will slow down when the ray pass from air to water, and will speed up when the light ray goes from air to water.

5) When the light passes from the the optically less dense medium (air) to the denser one (water) the light ray bends toward the normal (which Cleo described correctly). When the light ray passes from the denser medium (water) to the less dense medium (air) it will bend away from the normal.

C. Light slows down when it moves from air into water.(hope this helped)

Wind, solar and geothermal power are called renewable energy sources because _____.

(Video) Do Heavy Objects Actually Fall Faster Than Light Objects? DEBUNKED

They are inexhaustible.

Explanation:

Energy sources that are never ending are called renewable sources of energy. Solar power comes from Sun . Sun light never gets exhausted and is always present . So it is called renewable source. Similarly wind and geothermal energy also do not get exhausted even after using them repeatedly, on a large scale. Using these energy resources does not cause environmental pollution.

But when it comes to energy resources like fossil fuels, they are non renewable since the resources drain out if used on a large scale, over a period of time.

The correct answer for this is is ‘B’ or ‘The big Bang’

## FAQs

### Does Air Resistance Affect The Motion Of A Falling Object Differently When The Initial Velocity Of The? ›

With air resistance, acceleration throughout a fall gets less than gravity (g) because air resistance affects the movement of the falling object by slowing it down. How much it slows the object down depends on the surface area of the object and its speed.

Does air resistance affect the velocity of a falling object? ›

Air resistance and drag force affect the object's movement and velocity, relative to its shape.

How does air resistance affect initial velocity? ›

As a projectile moves through the air it is slowed down by air resistance. Air resistance will decrease the horizontal component of a projectile. The effect of air resistance is very small, but needs to be considered if you want to increase the horizontal component of a projectile.

How does a force of air resistance affect motion of falling objects? ›

When air resistance acts, acceleration during a fall will be less than g because air resistance affects the motion of the falling objects by slowing it down. Air resistance depends on two important factors - the speed of the object and its surface area. Increasing the surface area of an object decreases its speed.

Which factors affect the air resistance acting on a falling object? ›

The 3 things which affect the amount of air resistance acting on an object are its relative air speed, its aerodynamic form ( shape and size relative to the air mass), and the density of the air.

Do objects fall faster without air resistance? ›

Notice that the object's motion is not affected by its mass, weight, density, or any other measurement of its size. In fact, all objects fall at the same rate in a vacuum as long as the only force acting on them is gravity.

Why does air resistance increase velocity? ›

Answer and Explanation: Air resistance is caused by the collision of the air molecules with the surface of the object that is passing through it. As speed increases so too does the frequency of the collision of air molecules with the object. This results in an increase in air resistance.

What is air resistance and how does it affect an object? ›

Also known as 'drag,' air resistance is a force caused by air. The air particles hit the front of an object, causing it to slow down. The greater the surface area, the greater the number of air particles hitting the object and the greater the overall resistance.

What does initial velocity affect? ›

Initial vertical velocity changes throughout projectile motion. Its magnitude decreases when a object travels upwards and increases when it travels downwards. Initial horizontal velocity remains constant and does not change.

What happens to the air resistance of a falling object? ›

As an object falls, it picks up speed. The increase in speed leads to an increase in the amount of air resistance. Eventually, the force of air resistance becomes large enough to balances the force of gravity.

### What is the force of air resistance on a falling object? ›

The net external force is equal to the difference between the weight and the drag forces (F = W - D). The acceleration of the object then becomes a = (W - D) / m . The drag force depends on the square of the velocity. So as the body accelerates its velocity (and the drag) will increase.

Does air resistance increase or decrease the acceleration of a falling object quizlet? ›

How does air resistance affect the acceleration of falling objects? Air resistance slows the acceleration of falling objects. An object falls at its terminal velocity when the upward force of air resistance equals the downward force of gravity.

Which falls first the heavier or lighter object without air resistance? ›

Heavier objects hit the ground first as they have very less air resistance.

What is the effect of air resistance on the acceleration of falling objects What is the acceleration with no air resistance? ›

How does air resistance affect the acceleration of falling objects? Air resistance affects acceleration on falling objects by reducing it. Without air resistance, falling objects would accelerate much faster.

What would happen if there wasn t any air resistance to slow down falling objects? ›

If there were no air, the two objects would hit the ground at the same time. To slow down a fall of an object, you will want to create more drag. That's the goal of a parachute.

Does increased resistance increase velocity? ›

As resistance increases the difference in pressure which influences velocity decreases, which in turn reduces flow.

What is the relationship between velocity and air resistance? ›

The force of air resistance clearly depends on the velocity of an object moving through the air: the larger the speed, the larger the drag force.

What effect does air resistance have? ›

All moving objects are impacted by air resistance. Consider an airplane as an example of a body in motion. The speed of an airplane is influenced by air resistance; the air resistance opposes the airplane movement. The force exerted by air is in the opposite direction to the airplane movement and decreases the speed.

What affects air resistance the most? ›

Air resistance is mostly affected by air density, temperature, and pressure. The higher the air density, due to the aerosol in the air, lowers the objects' speed. The air pressure is also responsible for slowing down the speed. At high temperatures, the air velocity increases, reducing or increasing the speed.

What is the rule for initial velocity? ›

Concept of initial velocity:

Forces acting on any object will cause it to accelerate. Due to this acceleration velocity of the object changes. Therefore, the initial velocity is the velocity of the object before the effect of acceleration, which causes the change.

### How does initial velocity affects the range of motion? ›

How does the initial velocity of a projectile affect its range? Obviously, the greater the initial speed vi, the greater the range, as shown in Figure 5(a). The initial angle θi also has a dramatic effect on the range, as illustrated in Figure 5(b).

Is air resistance acceleration or velocity? ›

Air resistance is a force that depends on the velocity. This means that the force (and thus the acceleration) is not constant.

How to find velocity of free falling object with air resistance? ›

The Force of Air Resistance Fd = bv , where b is the coefficient of air resistance which depends upon the size and shape of an object as well as the properties of the fluid through which it is moving. The Definition of the Terminal Speed vt ≡ mg b .

What is the velocity at which a falling object travels when the force of air resistance exactly matches the downward force? ›

Terminal velocity is the constant velocity of a falling object when the force of air resistance equals the force of gravity. projectile motion. This section discusses how force and mass affect acceleration.

Does air resistance make heavier objects fall faster? ›

The less massive the object is, the more the force of air resistance slows the object down as it falls. If two objects were dropped on the moon, where there is no air, they would fall at the same rate no matter how much they differ in mass. The shape of the object can impact how much it is affected by air resistance.

Does acceleration increase in free fall with air resistance? ›

Acceleration does not increase in a free fall. The acceleration on the surface of the earth is approximately equal to 9 . 8 m s 2 . The velocity increases constantly but not the acceleration.

What happens to acceleration when air resistance is ignored? ›

If air resistance is ignored , then there is no acceleration in horizontal direction in projectile motion. Hence the particle move with constant velocity in horizontal direction.

What is the relationship between air resistance and terminal velocity? ›

The force of air resistance is approximately proportional to the speed of the falling object, so that air resistance increases for an object that is accelerating, having been dropped from rest until terminal velocity is reached. At terminal velocity, air resistance equals in magnitude the weight of the falling object.

Which velocity components would be affected by air resistance? ›

Since air resistance is caused by the relative motion between the layers, so the component of velocity with greater magnitude will get most affected. Vertical in the initial and final parts and horizontal in the intermediate path of the motion are affected the most.

What is free fall velocity with air resistance? ›

Near the surface of the Earth, an object in free fall in a vacuum will accelerate at approximately 9.8 m/s2, independent of its mass. With air resistance acting on an object that has been dropped, the object will eventually reach a terminal velocity, which is around 53 m/s (190 km/h or 118 mph) for a human skydiver.

### How to calculate air resistance of a falling object at terminal velocity? ›

The Force of Air Resistance Fd = bv , where b is the coefficient of air resistance which depends upon the size and shape of an object as well as the properties of the fluid through which it is moving. The Definition of the Terminal Speed vt ≡ mg b .

What happens to the force of air resistance on a skydiver as they fall? ›

This force of air resistance counters the force of gravity. As the skydiver falls faster and faster, the amount of air resistance increases more and more until it approaches the magnitude of the force of gravity.

What is the velocity of a falling object in air? ›

Velocity of a Falling Object: v = g*t

A falling object is acted on by the force of gravity: -9.81 m/s2 (32 ft/s2). Gravity will accelerate a falling object, increasing its velocity by 9.81 m/s2 (or or 32 ft/s2) for every second it experiences free fall.
